Struct DeviceVideoTrackConstraints 

pub struct DeviceVideoTrackConstraints {
    pub required: bool,
    pub device_id: Option<ConstrainString<String>>,
    pub facing_mode: Option<ConstrainString<FacingMode>>,
    pub height: Option<ConstrainU32>,
    pub width: Option<ConstrainU32>,
}

Constraints applicable to video tracks that are sourced from some media device.

Fields

required: bool

Importance of this DeviceVideoTrackConstraints.

If true then without this DeviceVideoTrackConstraints call session can’t be started.

device_id: Option<ConstrainString<String>>

Identifier of the device generating the content for the media track.

facing_mode: Option<ConstrainString<FacingMode>>

Describes the directions that the camera can face, as seen from the user’s perspective.

height: Option<ConstrainU32>

Height of the video in pixels.

width: Option<ConstrainU32>

Width of the video in pixels.

Implementations

impl DeviceVideoTrackConstraints

Constraints applicable to video tracks that are sourced from screen-capture.

pub fn new() -> Self

Creates new DeviceVideoTrackConstraints with none constraints configured.

pub fn device_id(&mut self, device_id: String)

Sets exact deviceId constraint.

pub const fn exact_facing_mode(&mut self, facing_mode: FacingMode)

Sets exact facingMode constraint.

pub const fn ideal_facing_mode(&mut self, facing_mode: FacingMode)

Sets ideal facingMode constraint.

pub const fn exact_height(&mut self, height: u32)

Sets exact height constraint.

pub const fn ideal_height(&mut self, height: u32)

Sets ideal height constraint.

pub const fn height_in_range(&mut self, min: u32, max: u32)

Sets range of height constraint.

pub const fn exact_width(&mut self, width: u32)

Sets exact width constraint.

pub const fn ideal_width(&mut self, width: u32)

Sets ideal width constraint.

pub const fn width_in_range(&mut self, min: u32, max: u32)

Sets range of width constraint.

pub async fn satisfies<T: AsRef<MediaStreamTrack>>(&self, track: T) -> bool

Checks whether the provided platform::MediaStreamTrack satisfies contained DeviceVideoTrackConstraints.

pub fn merge(&mut self, another: Self)

Merges these DeviceVideoTrackConstraints with another ones, meaning that if some constraints are not set on these ones, then they will be applied from another.

pub const fn required(&self) -> bool

Returns an importance of these DeviceVideoTrackConstraints.

If these DeviceVideoTrackConstraints are important then without them a session call can’t be started.

Trait Implementations

impl Clone for DeviceVideoTrackConstraints

fn clone(&self) -> DeviceVideoTrackConstraints

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceVideoTrackConstraints

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DeviceVideoTrackConstraints

fn default() -> DeviceVideoTrackConstraints

Returns the “default value” for a type.

impl From<ApiDeviceVideoTrackConstraints> for DeviceVideoTrackConstraints

fn from(value: ApiDeviceVideoTrackConstraints) -> Self

Converts to this type from the input type.

impl From<DeviceVideoTrackConstraints> for MediaTrackConstraints

fn from(from: DeviceVideoTrackConstraints) -> Self

Converts to this type from the input type.

impl PartialEq for DeviceVideoTrackConstraints

fn eq(&self, other: &DeviceVideoTrackConstraints) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
